Abstract

STATEMENT OF THE PROBLEM: Evaluation of the color stability of materials used for the fabrication of the base of complete and partial removable dentures provides important information in relation to their clinical service. The color stability of nylon-based polymers as denture bases, compared to that of acrylic resins, has not been extensively evaluated since to date.

PURPOSE: The aim of the present

MATERIALS AND METHOD: Twenty samples were evaluated in the present

RESULTS: After 100 hours of irradiation with UV light and thermocycling, color changes were tangible in both materials. After 200 hours of irradiation with UV light and thermocycling, both materials exhibited a decrease in glaze. In general, chromatic changes in the acrylic resin were more noticeable.

CONCLUSION: Accelerated aging affected the color stability of the acrylic resin and nylon-based polymer,

Keywords: Nylon-based polymer ; Spectrophotometer ; Color stability
